SIPHON.

SPECIFICATION forming part of Letters Patent No. 224,149, dated February 31880.

Application filed July 7, 1879.

marked thereon, making a part of this specifi# cation.

Our invention relates to sipllons; and it consists in the construction of a device whereby a suction may be created to obviate sucking by the mouth, as will be hereinafter Inore fullyV set forth.

In order'to enable o thers skilled in the art, to which our invention appertains to Ina-ke and use the same, we will now proceed to describe its construction and operation, referring tothe annexed drawing, which represents alon gitudinal section of our invention.

A represents the barrel or body of the suction-tube, provided with screw-caps B B' on its ends. O is ahollow piston passingthrough the cap B, and provided on its inner end with a follower, D. The cap B has a tubular projection, B2, on which the pipe E is fastened.

a is a valve in the end of the barrel. d is a valve in the handle or pulling-piece F, screwed e is a spring for holding the valve d to its seat. b is a guide for the stem of said valve, and f is a stop to prevent said valve from opening too far.

` The pipe E may be a rubber hose, or made of metal or other material, and when attached to the tubular projectionB its other end is then'placed in the liquid to be drawn.

The hand-piece F being grasped by the operator and drawn down, the valve a opens, and on 'the piston being pushed back closes and the valve d opens, thus producing a suction or partialvacuum, and the atmospheric pressure, act ing upon the liquid with a vacuum below the valve Va, causes the liquid to liow and open both valves', so that the liquid will find free egress out through the hollow piston. Now, by pushing the plunger back while the stream is running, a shut-oitl is obtained by the end of the plunger coming against and closing the valve a, thus enabling the operator to control the flow of the liquid at will, or by partially closing it to reduce the size of the stream.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination, of the barrel A, having screw-caps B B', the pipe E and handle F, the hollow piston G, with follower D, valves a d, spring e, guide b, and stop f, all constructed and arranged to operate substantially Vas and for the purposes herein set forth.

In testimony that we claim the foregoing we have hereunto set our hands and seals this 1st day of July, 1879. p
